What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

Introduction to the method of evaluating the quality of lubricating oil

  The three major tests for evaluating the quality of lubricants are more critical. As a standard for comprehensively evaluating lubricant quality, countries around the world have basically become consistent, establishing a quality standard consisting of four parts: physical and chemical indicators of lubricants, simulation tests, bench tests, and driving tests. system.

The physical and chemical indicators are the basis. The physical and chemical indicators used to measure the basic performance of lubricants include: kinematic viscosity, low temperature dynamic viscosity, viscosity index, flash point, pour point, sediment, moisture, foam, residual carbon, neutralization value, sulfate ash content And the content of various elements and so on.These physical and chemical indicators are only the basic indicators for measuring lubricating oil. If even the physical and chemical indicators are unqualified, then the following simulation tests and bench tests will not be able to talk about.

The simulation test is the evaluation method. The first is the simulation test. During the research and development of the oil product, the technicians found that the physical and chemical indicators of the oil product cannot explain the problem or reflect whether the mechanical friction pair is easy to use. The main test It consists of the following parts: the coking plate test method and heat pipe test method reflecting the cleanness, dispersion and anti-oxidation of automotive lubricants; the multi-metal oxidation test method and film oxidation test method reflecting the oxidation resistance of automotive lubricants at high temperatures; reflection The speckle test method for the ability of automotive lubricants to disperse sludge; the high-temperature four-ball machine abrasion test method reflecting the anti-wear level of automotive lubricants. These simulation tests can only simply reflect the working conditions of the engine, and cannot simulate the influence of the engine on the performance of the oil, especially under the complex conditions and working conditions. In addition, the simulation test method generally adopts comparatively intensified or generalized test conditions. However, the strengthening will be unrealistic, because in the whole process of the engine operation, various comprehensive factors are combined, which affect the oil’s anti-oxidation, cleaning, dispersion and anti-wear capabilities. It is impossible to perform the simulation test of a single performance evaluation. The method is truthfully measured and evaluated, so the various simulation test methods and their evaluation indicators are basically not reflected in the engine oil specifications.

The bench test reflects the problem more truthfully. In order to truly reflect the use of oil, and at the same time, it can be recognized by the engine manufacturing department. A bench test to evaluate the performance of lubricating oil has been developed.The bench test is to install a representative engine in a test room, perform an evaluation test for a certain period of time under approved or recognized control conditions, and wait for the engine manufacturer to negotiate and determine various performance indicators before the test. After the rack test is completed, it will be judged; observe whether the testable oil product meets the requirements; if the oil product's various judgment indicators are within the limit range, it can be considered that the oil product has been initially approved and obtained the qualification of the type of oil product. certificate.In principle, it can supply the market.After the above three tests, the quality of the lubricating oil can be fully guaranteed to meet the engine oil requirements of various engine manufacturers.
